Who runs ThunderStudy AI Mind Map?

There is no company or team behind it. Every page, tool and fix comes from one person, which is why the site stays small, fast and free.
What is the mission of ThunderStudy AI Mind Map?
Good study tools should not depend on what a student can pay. ThunderStudy AI Mind Map exists to give every student, whether preparing for CUET, SSC, Banking or any other subject, a free way to turn a long chapter or a big syllabus into a clear, connected picture.
No account, no card and no paid tier. The only limit is a fair-use cap of 3 maps a day and 12 a week, so the free AI stays available for everyone.
